Specification of Letters Patent. Application filed November 15, 1913.

Patented July 28, 1914. Serial No. 801,107.

To all whom it may concern Be it known that I, HEINRICH Korrnns, a subject of the King of Prussia, and residing at lIssen-on-the-Ruhr, Germany, have invented certain. new and useful Improvements in the Method of and Means for Working Coke-Ovens, of which the following is a specification.

In working blast furnaces and similar ore melting devices, a superior coke of uniform quality is required which is best obtained in horizontal coke ovens from coal of small eration has been completed, raised through the body of the charge to grain yielding a high percentage-say 80% or more or less--of coke. In the coking of this coal, a difficulty arises from the fact that the same if tightly packed will expand under the action of damaging and ultimately destroying the ovens. This tight packing, more particularly of the lower strata of the coal charge, results from the unavoidable high drop of the coal from the charging hoppers into the coking chambers.

The object of the present invention is to overcome this difliculty and to so loosen up the coal in the oven that any detrimental effects owing to the subsequent swelling of the coal particles are obviated. In other Words the loosening of the coal will provide diminutive interstices between said particles within which the swelling may take effect without increasing the volume of the mass, so that in this way the walls of the oven are relieved from undue pressure.

--In carrying out my invention, I place a rake orother loosening member upon the bottom of the coking chamber prior to the introduction of the charge, so that as the latter is filled in, said member will become embedded therein. After the charging opthe rake is loosen it up in the the coking process.

In'order to reduce the number of coke oven accessories, it is preferred, to employ the leveling rod or part thereof as raking member. the same being well adapted for this purpose,'although different means may obviously be adopted without departing from the spirit of my invention. I

In the accompanying drawing: Figure 1 is a sectional elevation of a coke oven embodying my invention, Fig. 2 a, detail of a bipartite loosening member, Fig. 3 an enlarged manner desired prior to heat, thereby frequently 16 is introduced into the tilled in to the height desired.

cross section on line 3-3, Fig. 1, and Fig. 4 a detail of part of the loosening member.

The coke oven 10 is provided with a plurality of horizontal coking chambers 11 that receive their charge from the usual hoppers 12 mounted on a carriage 13 traveling along the top of the oven. A second carriage 14 travels along the front of the oven and supports the usual discharge ram 15 and also a combined levelingand loosening member A which may be reciprocatcd between rolls 17 in the usual manner, when employed for levcling purposes. As-shown, this member is composed of two sections 16, 16 that may be coupled by means of a key 18 or otherwise. Of these, the front section 16;which constitutes the raking member proper is provided with a plurality of laterally extending tines 19 as clearly illustrated in Figs. 1, 2 and 3. Rake 16 is adapted to be engaged near its ends by a pair of hooks 2O suspended from ropes 21 that pass through corresponding apertures 22in the open roof and may be uniformly wound upon a drum 23 by an electromotor 24 supported on carriage 13.

f a coking chamber has been emptied and is to be filled with a fresh charge, the coupled leveling and loosening member 16, chamber through openin 25. Hooks 20 are next connected to section 16, key 18 is removed, and section 16 is slightly retracted to occupy the position illustrated in Fig. 1. Section 16 is then lowered until it rests upon the bottom of the coking chamber, whereupon the charge is Section 16 1s now raised through the coalcharge to loosen the same, section 16 is slightly advanced to be recoupled to section 16, hooks 20 are withdrawn, and the parts 16, 16 are rcciprocatcd to level the charge in the usual manner.

I claim:

1. Method of preparing a charge for a top-charged oven chamber which consists in dropping finely grained coal from above into said chamber thereby effecting a packing of said coal, and subsequently loosening up said packed coal.

2. Method of preparing a charge for a top-charged oven chamber which consists in dropping finely grained coal from above into said chamber thereby effecting a packing of said coal, and subsequently loosening up said packed coal from the bottom upward.

3. Method of preparing a charge for a topcharged oven chamber which consists in dropping finely grained coal from above into said chamber thereby effecting a packing of said coal, and subsequently raising a loosening member through the coal.

lsMethod of working a coke oven which consists in placing a loosening means on the bottom of the coking chamber, filling a charge of coal over said means, and raising said means through the coal.

5. A coke oven having a coking chamber, a coal loosenin member, means for depositing said mem ofi' said bottom.

er on the v bottom of said chamber, and means for raismg said member composed of two sections, means for conplmg said sections, tines on one of said sections, and means for raising said last named 4 rod-section.

7. In a coke oven, having a forward detachable section, means for. advancing said rod to introduce, said section into a coking chamber at the top a coal loosening rod thereof, means for releasing the rod-section, v

and means for vertically moving the released rod-section within the coking cham--- ber.
